1) Message boards : Sixtrack Application : please, remove non-optimized application SixTrack for 32 bit systems (Message 42560)

Dear Sirs.

I kindly ask you to remove completely from the LHC@home project a non-optimized application SixTrack for 32 bit systems: https://lhcathome.cern.ch/lhcathome/apps.php

Look at the page: https://lhcathome.cern.ch/lhcathome/apps.php where an unoptimized 32 bit application SixTrack produces 1822 GigaFLOPS, when the optimized ones for avx / sse2 just 341 / 415 GigaFLOPS an average.

That is, in fact, that turns out that all users of 32 bit systems are crunching for 6 hours with an unoptimized application. In case you remove it, all users will begin to crunch at avx/sse2-optimized applications in just 2 hours.

In other words, huge opportunities are being lost doing it.

Or maybe is there any explanation to this?
